This included fitting the crawler excavator with a 9 metre boom and a dipper stick
6 meters in length.
These booms have reinforced dipper stick
Bucket and dipper stick
breakout forces have also increased, together with a significant increase in the hydraulic flow from the pumps to 2 x 360 litres/min.
They take into account the movement and angle of the bucket, boom and dipper stick
to give continuous depth control indication on the in-cab display.
"It's built right into the dipper stick
, so you don't lose any breakout force," says Schaefer.
There are options to be considered, such as tire sizing and axles, two-wheel or four-wheel drive, cab or canopy, extendable dipper stick
or a standard dipper.
Other features include: a single, center mounted loader dump cylinder has fewer wear points; tilt-up hood and grill for better serviceability; a wide stabilizer spread increases stability when operating to the side; and a dry, wear compensated extendable dipper stick
requires less maintenance.
In backhoe mode, the L48 delivers an 11 foot 1 inch digging depth, a maximum dipper stick
digging force of 3,968 pounds and a maximum bucket digging force of 5,908 pounds.
